March, spring breeze. On the occasion of the Arbor Day, in order to advocate green life, Chongqing Tianqi Lithium and Chongqing Hi-Tech Zone Management Committee jointly carried out the activity of "Learning from Lei Feng - planting trees to add new green". Under the guidance of greening technicians, we divided the work and planted more than 30 citrus trees. This activity not only raised the awareness of planting trees and protecting the ecological environment, but also strengthened the spirit of teamwork and mutual assistance.
